Video Formats & Rates (Cont’d)
Standard Definition Aspects
480i and 576i modes may also be set up for use in Anamorphic 16:9, Letterboxed 16:9, or
cropped 4:3 aspects.
1080sF/1080PsF
For purposes of brevity and clarity, the 1080sF nomenclature is used in this manual and in
the HD-RH1 operation to stand for what is also known as 1080PsF (Progressive
Segmented Frame).
Doubled 720p Frames
To accommodate certain recording decks available, the slower frame rates for 720p
(23.98-30Hz) have the option to be “pulled-up” to either a double (2:1 ratio) frame rate,
or a 3:2 style (actually a 2:5 frame-to-carrier ratio). The nomenclature used for this
device in the HD-RH1 is
720p24n60
, which means 720p resolution with 24-frame native
content on a 60Hz carrier.

OPERATIONAL NOTES:
•
The Dual-Link signal for 1080p50, 1080p59.94, & 1080p60 is implemented per
SMPTE-372. Either link used independent of the other will appear as a single 1080i
4:2:2 signal. The Video Payload ID embedded in the digital stream can be used to
differentiate between 1080p and 1080i when in this mode.
•
The HD-RH1 automatically switches to SD-SDI (SMPTE-259) when in
480i
and
576i
. The only mode available for SD-SDI is
SL 422.
